DEFINITION

Classification: 29/592

METHOD OF MECHANICAL MANUFACTURE:

(under the class definition) Process of mechanical manufacturing.

(1) Note. See the definition of "Manufacturing" in the Class 29 definition Glossary.

(2) Note. Whereas Class 29 is the generic mechanical manufacturing class; manufacturing by chemistry, electrochemistry, electricity, or the related arts is provided for in the chemical and electrical classes. See the classes listed on pages I-6 through I-10 in the front of the Manual of Classification under "I. Chemical and Related Arts" and "II. Communications, Designs, Radiant Energy, Weapons, Electrical, and Related Arts."

(3) Note. A complete search for any process of manufacturing a particular article may include the class providing for that article.

(4) Note. A process as defined above, whether comprising a single or a plurality of operations, is included in Class 29, subclasses 592+, only when no other class provides for the same. A typical patent of this subclass recites a plurality of steps or operations separately provided for in different classes, none of which provide for the combination.

(5) Note. Many of the preceding subclasses in Class 29 include apparatus and include a process which is a function of an apparatus; see, particularly, the subclasses directed to the manufacture of "special articles" (i.e., subclasses 1.1 to 25.42, above).

(6) Note. Patents are classified here regardless of the material operated on and/or the number of operations involved unless provided for elsewhere. See the Class Definition, paragraph 2, of this class (29).

(7) Note. Measuring, testing, recording, article handling, conveying, and cleaning, per se, are not considered manufacturing processes for this class (29). SEE OR SEARCH CLASS
